DLMS Supplement 947I, Inventory Adjustment 

b. Description of Change: This change updates DLMS supplement 947I to carry unique item 

identifier (UII) data for unique identification (UID) of assets. Component system changes which 

are required to support the integration of UII data are not identified in this change and must be 

addressed by the Components. The DLMS and DOD 4140.1-R, DOD Supply Chain Materiel 

Management Regulation, provide for unique item tracking (formerly called serial number tracking)

ADC 156 

Att 

for specific DOD UIT programs. The inclusion of UID UII data in the DLMS facilitates UIT for 

those items that fall under the UID policy criteria of ‘serial managed’ assets. Initial inclusion of the 

data in DLMS is intended to facilitate tracking by UII for DOD UIT programs, but it also positions 

DLMS transactions for wider use of UID if requirements are identified as UID logistics and 

financial implementation policies evolve. 

c. Procedures: Modify DOD 4000.25-M, DLMS Manual as follows: 

(1) ADC 127 updated DLMS manual front matter to include unique item identification related 

definitions and acronyms as provided below for ease of review: 

Terms and Definitions

Unique Identification (UID) of Items. The application of a set of data elements that is globally 

unique and unambiguous, ensures data integrity and data quality throughout life, and supports 

multifaceted business applications and users. 

Unique Item Identifier (UII). An identifier used in unique item tracking programs to uniquely 

identify an individual asset used within DOD. The UII may be derived from a DOD-approved 

commercially-accepted identification methodology [e.g., Vehicle Identification Number (VIN)] or a 

composite structure defined by the DOD [refer to UID Construct 1 and UID Construct 2]. 

Formation of the UII relies upon two primary methods of serialization: (1) Serialization within the 

enterprise and (2) Serialization within the original part number of the enterprise. Regardless of 

which numbering system is used, the UII must include the Enterprise Identifier. Refer to OSD 

policy and supporting documentation for specific guidance at http://www.acq.osd.mil/dpap/UID/. 

Refer to MIL-STD-130L for specific guidance marking of U.S. Military property. 

Acronyms and Abbreviations:

UII Unique Item Identifier 

UID Unique Identification 

 (2) This ADC complements and supports PDC 147, November 4, 2004, DLMS Unique Item 

Tracking (UIT) Procedures – New Chapter 19 (Supply/UIT). Please note that PDC 147 is currently 

being revised for staffing as PDC 147A, based on discussion at the December 9, 2004, Unique Item 

Tracking Committee meeting. 

 (3) Modify DLMS Supplement (DS) 947I. Mapping and associated notes for ANSI ASC X12 

formats are identified in the table at paragraph 7 below. All changes are at the ANSI ASC X12 

Version 4030. Changes will be carried over to the DLMS XML equivalent transaction. 

DS 947I intends to support the following data configuration. 

[1] The UIT loop (2/LX /150 loop) provides specific UID information and provides 

flexibility to accommodate tracking by UII or serial number. Providing for UIT by serial number is 

a transitional requirement which may be required until the Components fully implement the UID 

concept, and tracking by UII, across DOD. 

[2] The UIT loop is repeated for each item to be uniquely identified.

ADC 156 

Att 

5. REASON FOR CHANGE: 

a. OSD policy for UID states that the Unique Item Identifier (UII) shall be the primary or 

alternate pointer or key data element for the automated information systems. In support of this 

requirement, logistics transactions must identify the UII. This change incorporates the UII as 

defined under UID policy, within DLMS logistics exchange transactions. 

b. A goal of unique identification of items is to help achieve clean audit opinions on DOD 

financial statements. As the Financial policy and requirements for UID evolve, they may influence 

future UID implementation in logistics transactions and systems. 

c. The UII terminology that had been carried in DS 947I prior to this change was 

comparable to the serial number, but did not equate to a UII under the new DOD UID definition 

since a serial number lacks “uniqueness” when used alone. This change introduces the revised 

understanding of the term UII to DS 947I. 

d. This change migrates DS 947I incorporating UID data to ANSI version 4030 to take 

advantage of the longer field length provided for reference identifier 127 in the N9 segment. 

Reference identifier 127 increased from 30 positions to 50 positions in ANSI version 4030. While 

the 50 position field length is still not adequate to carry the 78 position UII in one location, the 

increased length allows the UII to be carried in a combination of two data areas rather than three as 

would be required with a 30 position data field. DLMSO has submitted an ANSI data maintenance 

request to increase the reference identifier 127 field size to 80 positions, for future use. 

6. ADVANTAGES AND DISADVANTAGES: 

 a. Advantages: Although specific logistics policy and requirements for implementing UID 

have not been defined, this ADC supports the UID concept by incorporating UID functionality in 

DS 947I, Inventory Adjustment transaction.

b. Disadvantages: None specifically identified; however UID implementation policy is 

evolving and additional changes may be required to modify or enhance the transactional exchange 

as outlined in this change.

7. IMPACT: 

a. Automated Information Systems. Component system changes which are required to 

support the integration of UID UII data are not identified in this change and must be addressed by 

the Components.

DLMS Notes:

1. Must use the 2/N9/1600 segment in Product Transfer

identified is subject to UIT requirements. 

2. This segment supports item identification based upon

3. This segment also provides for use of a batch/lot 

number, when applicable. 

4. Use multiple iterations of 2/N9/1600 segment within the 

2/LX/1500 loop, to provide identifying information for an 

item as needed. 

5. Use in CAV Inventory Adjustment (Condition Code)

12. 2/N901/1600 Added qualifier “U3” w/ the following DLMS notes: 

U3 Unique Supplier Identification Number 

DLMS Note: 

1. Use to identify the UII. Place UII value in N902. 

If UII is longer than 50 positions, place remainder of UII in 

N903. An ANSI data maintenance request has been 

prepared to request a new code qualifier for Unique 

Item Identifier for future use. 

2. DLMS enhancement. See introductory DLMS note 

4a. 

Identifies the Unique 

Item Identifier (UII) 

value, and provides 

guidance for 

placement when UII 

value is longer than 

50 positions. 

Per DOD UID policy, the 

UII can be up to 78 

characters, however 

existing ANSI structure 

for the N9 segment does 

not provide a field large 

enough for a 78 position 

UII. To allow for the 

longer length, the UII 

value is split between 2 

locations (N902 and 

N903). 

NOTE: DLMSO has 

submitted an ANSI data 

maintenance request to 

increase the reference 

identifier 127 field size 

(which is used at N902)

use.
